United States Patent 3,469,584 CIGARETTE Max J. Doppelt, 1920 W.Sunnyside Ave., Chicago, Ill. 60640 Filed Feb. 9, 1967, Ser. No. 614,974Int. Cl. A24d 1/04 US. Cl. 131-10 1 Claim ABSTRACT OF THE DISCLOSURE Acigarette having a tobacco section and a mouthpiece section, with themouthpiece section formed of hollow tubular member provided with aplurality of circumferentially spaced openings or perforations, with apaper or the like covering the tubular member and openings orperforations, which paper or the like is porous and absorbent andpermits outside air to be drawn into the tubular member through saidcovered openings to adm'ix with the smoke drawn into the tubular memberfor the purpose of reducing the quantity of particulate or tar andnicotine and providing a cooler smoke.

As is well-known, the smoking of cigarettes produces a particulatematter which is commonly called tar, and also produces a nicotine, bothof which are injurious to the health of the smoker. Various attemptshave been made to reduce the particulate matter or tar and the nicotine,such as, for example, the use of various filters between the tobacco endof the cigarette and the other end which is inserted in the mouth.However, such filters and the various means used have not appreciablycaused any significant reduction in the quantity of particulate matteror tar and the nicotine reaching the mouth of the smoker. The object ofthe present invention is to provide a cigarette in which the particulatematter (tar) is considerably reduced from that produced by thecigarettes now on the market, whether they be filtered or unfiltered.This invention also results in a reduction of the nicotine.

This invention also produces a cigarette smoke which commingles with theair drawn into the cigarette so that the smoke reaching the smokersmouth is considerably cooler than is possible with conventionalcigarettes. It reduces or eliminates the usual biting effect produced inthe smoking of conventional cigarettes and produces a smoke which isrelatively mellow and mild. With this invention cool air is drawn intothe mouthpiece section of the cigarette along with the smoke from thecigarette and this cools the smoke and creates an immediate condensationof particulate matter in the mouthpiece section. The paper covering isalso absorbent. The absorbent paper over the tubular member helps absorbthe tar and particulate and reduces considerably the amount of tar orparticulate matter which would normally enter the mouth with the smoke.

Another object of this invention is to provide a cigarette with atubular unobstructed mouthpiece section between the tobacco end and theend portion which is put in the mouth so that the smoker gets thebenefit of the same taste as he would if his month were on the tobaccoend of the cigarette.

Other objects will become apparent as this description progresses.

In the drawings:

FIG. 1 is a central longitudinal sectional vie-w of the cigaretteforming this invention.

FIG. 2 is an enlarged sectional view, showing particularly themouthpiece section of the cigarette shown in FIG. 1.

FIG. 3 is a section view taken on lines 33 of FIG. 2.

FIG. 4 is a view of a cigarette of a modified construc- "ice tion inwhich the paper or the like surrounding the mouthpiece section overlapsthe inner end of the tobacco portion, and

FIG. 5 is a view of a further modification in which the inner end of thetubular member is inserted into the inner end of the tobacco portion ofthe cigarette.

Referring first to the embodiment shown in FIGS. 1 to 3 inclusive, thecigarette comprises a front portion which is the tobacco section and isgenerally designated by the numeral 10, and a rear portion which is themouthpiece section and is generally designated by the numeral 12. Thetobacco section 10 of the cigarette consists of the tobacco 14 containedwithin a non-porous paper wrapping 16 which is of conventionalconstruction commonly used in the manufacture of present-day cigarettes.

The rear portion or mouthpiece section 12 of the cigarette includes ahollow tubular member 18 which may be made of plastic, cardboard, or thelike, and which is provided with a plurality or circumferentially spacedopenings or perforations 20. The spaced openings or perforations 20 arecircumferentially positioned on said tubular member substantially theentire length thereof. Suitably secured to the outside of the hollowtubular member 18 is a sheet of paper or the like designated by thenumeral 22. This paper is specially made from natural fibers and is bothporous and absorbent. While the paper 22 covers the openings orperforations 20 it does not prevent the cool air from being sucked ordrawn into the interior of the tubular member 18 through saidperforations.

The inner or rear end 24 of the tobacco section 10 of the cigarette ispositioned adjacent and contiguous to the front of tubular member 18, asbest shown in FIGS. 1 and 2, and the two are joined or connectedtogether by a band 2 6 having suitable adhesive characteristics. Thediameter of the tubular member 18 and the paper 22 around it is equal tothat of the diameter of the tobacco section 10 so that when the band 26is adhesively secured to both the tobacco section-10 and the mouthpiecesection 12 it overlaps a portion of each and joins them together as anintegral unit to form the cigarette.

The modification shown in FIG. 4 includes a tobacco section 28 and amouthpiece section 30. The tobacco section comprises the tobacco 32enclosed within a wrapper 34, however, the wrapper 34 around the tobaccoterminates short of the inner end of the tobacco 32, as best seen inFIG. 4. The hollow tubular member 36 of the mouthpiece section 30 isidentical to the tubular member 18 with the spaced openings therein. Theporous and absorbent paper 38 surrounding the tubular member 36 extendsbeyond the front end of the tubular member 36, as indicated by thenumeral 40, and forms a sleeve and said paper sleeve 40 encompasses theinner uncovered tobacco end 42. A band 44 having suitable adhesiveoverlaps the covering 34 and the sleeve 40 and unites the two sections28 and 30 as an integral unit.

The modification shown in FIG. 5 comprises the tobacco section 46containing the tobacco 48 within the conventional paper wrapping 50. Inthis embodiment the paper wrapping 50 extends rearwardly beyond theinner end of the tobacco portion. Said paper wrapping extension isdesignated by the numeral 52. The hollow tubular member 54 of themouthpiece section has spaced openings 56 and is covered with a porousand absorbent paper 58, except that the front end of the tubular member54 adjacent the rear end of the tobacco section remains uncovered sothat the front portion of the tubular member may be inserted into therear end 52 of the tobacco sec tion 46, which forms a sleeve to enclosethe front end of the tubular member 54. A band 60, similar to thatpreviously described and having adhesive characteristics overlaps thepaper of the tobacco section and that of the mouthpiece section to unitethe two sections.

The tubular member of the mouthpiece section in all of the embodimentsis approximately 1% inches in length, therefore, when a person has thecigareete in his mouth there is no contact with the tobacco and thetobacco end of the cigarette would be spaced approximately 1% inchesfrom the rear end of the mouthpiece section. When the cigarette islighted and is being smoked, cool air is sucked or drawn into thetubular member from the outside of the tubular member and said airpasses through the porous and absorbent paper around the tubular memberand through the perforations or openings 20 and into the inside of thetubularmember. In the tubular member the cool outside air commingleswith the smoke which is likewise drawn into the tubular member from thetobacco section. The air drawn into the tubular member through theopenings 20 being cooler than the smoke causes a speedy condensation.The condensation is heavier than the smoke and therefore the particulatematter (tar) drops from the smoke stream and clings to the inner wall ofthe tubular member and is also absorbed by the absorptive covering orpaper 22 (or 38 and 58 in FIGS. 4 and 5) over the tubular member. Thisproduces a dry smoke and substantially reduces the quantity of tarand/or particulate matter which is objectionable to cigarette smokersand is the cause of various physical ailments which are induced bysmoking. This invention also reduces the quantity of nicotine producedby the cigarette. The mouthpiece section of the cigarette absorbs and/orretains the tar and nicotine and thereby prevents it from reaching thesmokers mouth. The smoke that is drawn into the mouth is precooled inthe tubular member and this results in a milder and mellower type ofsmoke.

Since there is no obstruction in the tubular member between the tobaccoend of the cigarette and the mouth, the smoker gets the benefit of thesame taste in his mouth as if he had his mouth on the tobacco end of thecigarette, and this taste is entirely different from the taste where apadded filter or obstruction is in the mouth end of the cigarette, as iscommon with a good many types of cigarettes on the market. No tobaccoworks its way into the tubular member and consequently no tobaccotouches the mouth of the smoker.

The covering 22 (or 38 or 58) which surrounds the tubular member is aspreviously described and may comprise a paper or other material havingporous and absorptive qualities. The said paper or covering surroundingthe tubular member is permanently and integrally secured to the tubularmember. Said paper or covering surrounding the tubular member should betreated to make it moistureproof so that when the tubular end of themouthpiece section is in the persons mouth the covering paper does notdisintegrate or stick to the smokers lips. Said paper may be chemicallyprocessed, for example, the paper may be coated or covered with siliconeand its several solvents.

Various tests have been made by a reputable and wellrecognized testinglaboratory and these tests show that with the use of this invention thequantity of particulate or tar is substantially reduced as compared tothe quantity or particulate or tar produced by present-day cigarettes.There is also an appreciable reduction of nicotine by the use of acigarette formed in accordance with this invention.

This invention results in economies both as to the materials used in themanufacture of cigarettes and in the manner of manufacturing thecigarettes.

It will be understood that this invention may be used in connection withcigars, wherein the perforated tubular member covered with a porous andabsorbent paper hereinbefore described is secured to the inner (rear)end of the cigar so that it becomes a part of the cigar, as it does withthe cigarette herein described, and the term cigarette includes cigar.

It will be understood that various changes and modifications may be madefrom the foregoing without departing from the spirit and scope of theappended claims.

What is claimed is:

1. A cigarette comprising a tobacco section and a mouthpiece section,said tobacco section having a nonporous wrapping around the tobacco,said mouthpiece section comprising a hollow tubular member provided witha plurality of circumferentially spaced openings along substantially theentire length thereof, the outside diameter of said tubular member beingsubstantially equal to the diameter of said tobacco section andconstituting an extension thereof and a non-perforated porous andabsorbent covering surrounding said tubular member and said openings inabutting engagement with said nonporous wrapping, and means sealing saidabutting engagement, said non-perforated porous and absorbent coveringpermitting the air to be drawn into said tubular member during smoking,in which the outside air drawn into the tubular member produces a rapidcondensation which is heavier than the smoke entering the tubular memberand in which the particulate matter drops from the smoke 40 stream andclings to the inner wall of the tubular member and is also absorbed bythe covering around the tubular member, said mouthpiece section having adiameter throughout substantially equal to the diameter of the tobaccosection.
